TEM PORARY FILE.

SPECIFICATION forming part of Letters Patent No. 438,574, dated October 14, 1890.

' Application filed August 27,1890. Serial No. 363,177. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER DoM, a citizen of the United States, residing at Mount Healthy, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Temporary Files, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof. 7

My invention consists of a double-arched file for temporarily filing letters or other papers in such a manner as that any one of them will be readily accessible, and also the mechanism for operating same.

In the accompanying drawings, Figure 1 is a perspective view of my improved file, the dotted lines indicating the position of the arched wires when thrown outward to permit of a paper being placed on or removed from the stationary vertical wires. Fig. 2 is a bottom view of the base of the file, the latter being removed from the board or tablet to which it is attached, showing the preferred form of mechanism for retaining the arched wires in contact with the vertical stationary wires or away from the latter, as desired, the dotted lines indicating the position of the relative parts when the arched wires are thrown outward or opened. Fig. 3 is a bottom view of the base of the file (on a diminished scale) removed from the tablet, showing the preferred form of platefor covering and protect-.

ing the operative mechanism within said base.

My improved temporary file is preferably constructed as follows: The base A is cast or struck up hollow in order to receive and retain the operating mechanism, the bottom of said base being provided with a suitable lid or coverB to protect the internal mechanism in shipment. This lid may be dispensed with Without departing from my invention, as the base may be connected direct to the tablet Without said lid, if so desired. To the front portion of the base A are connected the ver tical stationary wires 0, the top portion of said Wires being beveled away, as shown, to permit of the arched vibrating wires D coming in contact with said beveled portion of the stationary Wires, and thus form a continuous circuit from front to rear of said base. The stationary wires may be either hollow or solid, as desired. The arched vibrating wires D are made to pass through the rear of the base, and are rigidly connected to outer end portions of the toothed segments E and E, as shown in Fig. 2, said arched Wires being retained in said base in a vertical rotatable position by means of said segments and the outer collars e, as shown in Fig. 1.

As shown in Fig. 2, the toothed segments E and E mesh, the latter having one end of an S-shaped spring F connected thereto, the other end of said spring being connected toa suitable lug, as f, made fast to the inner face of the base. is almost on a line horizontal with the pivotal It will be seen that the stud f points of said segments, and so soon as the point of connection 6 on segment E is brought either above or below said horizontal line the tension of said spring will force said segments to their extreme limits either forward or backward. This forward and backward tension of the spring when connected to one of the segments, as shown, has the tendency to retain the free ends of the arched wires D in contact with or away from the stationary wires 0, the rear of said wires D being rigidly connected to the said segments as aforedescribed, and any rotary motion imparted to said segments impart a corresponding vibratory motion to the outer or free ends of said wires.

Instead of the Sshaped spring, any suitable form of spring or springs may be employed for accomplishing the aforedescribed result.

The operation of my improved temporary file is as follows: To file a paper, the operator takes hold of or puts pressure against the downward portion of one of the arched wires D, and any outward movementthereof causes a corresponding movement of the other arched wire through the medium of segments E and E, and so soon as the point e 011 segment E has passed a line horizontal with its pivotal point said wires will be forced and held out ward through the resiliency of spring F when the paper is placed over the stationary wires 0. Having placed the paper in position over wires 0, the vibrating arched wires are brought back in contact with said wires 0 by giving the said arched wires an initial impetus, at which time the spring or springs will act to bring said wires together at their meeting ends, as shown in Fig. 1.

The advantages of my improved temporary file are apparent. The mechanism for operating the arched vibrating wires is cheap of manufacture, simple in construction, and reliable in operation. Any desired paper may be removed from the file without removing those subsequently filed. The construction is such that the base can be easily removed from the tablet H, and a number of files compactly nested for shipment.

It is evident that the segments E and E may be of any desired configuration other than that shown; and, if desired, two complete gears may be employed in place of said segments, the lower extremities of the arched vibrating wires being in this latter case cen trally connected to said gears, the construction shown, however, being preferredviz., the toothed segments.

What I claim as new, and desire to scour by Letters Patent, is

1. In a temporary file provided with stationary vertical wires made fast to the base and arched vibrating wires adapted to meet the said stationary wires, as set forth, the toothed segments to which the ends of said arched wires are connected, and suitable springconnection for operating said segments, for the purposes set forth.

2. A temporary file composed of base A, stationary vertical wires 0, arched vibrating wires D, connected at one end to the toothed segments E and E, or their equivalents, and a suitable spring-connection for operating the latter, substantially as set forth.

3. In a temporary file provided with doublearched vibrating wires, substantially as set forth, the means herein shown and described for operating said wires, the same consisting of toothed segments E E, and spring F, the latter being connected at one end to one of the segments and at the other end made fast to a stationary point, as f, for the purposes set forth.

4. A temporary file having a base A, stationary wires 0, and arched vibrating wires D, connectedto the toothed segments E and E, spring F, and cover 13, all combined substantially as set forth, and suitable means for connecting said base to the tablet.
